I'll be honest, paid calc software just seems like a scam to me (not technically, but with tens of thousands of programs for free on ticalc.org...). If that's the only place to get it then you'll just have to make your own versions until somebody can crack the (probably) RSA encryption. At current state-of-the-art, that'll take a trillion-ish years.

How can you determine if it's RSA encrypted or something more trivial to crack?

Sorry, I don't have my nspire on me, but those just look like partial files. What makes you think they are the same as the full version (without the key) ? I would think they'd offer just a simple trial version and give you the full download (if it even exists) after you pay.

Personally, I don't think it's worth even the time to disassemble or crack based on this thread.

I'm not sure if the trial is the same document as the full version but according to their website when you purchase an app you have to send them the last 8 digits of your 27-digit TI-Nspire's Product ID which I'm assuming they put in a list or something with other registered calcs (other people who have purchased the app) and the app then checks that against that list and allows you to access the full features. That's just my guess on how it works but not really sure.

I saw that thread on reddit you linked but it doesn't really say anything about getting the programs for free, more just people commenting whether or not the calculator itself is worth it or not (usable in the classroom).

At the end of the day aren't TNS files just LUA code, I'm sure it could be decompiled on a pc and be further analyzed no?

There are legal issues involved with reverse engineering, especially if it risks "taking away someone's livelihood."

If they need an ID then that means they probably compile a special version that can only be run on that calc (or calcs with those matching digits). That way people can't just post the binary files and everyone have access It is highly unlikely that their trial versions are full as it would be complicated to allow up to 100000000 different codes to "unlock" it.

In that case, it might actually be a simple way to crack the security, but you would have to buy a copy first.

Finally, please don't double-post like that. You can just edit your post to add more

Yeah I guess the entire ordeal isn't really worth the time (probably not even possible). Guess I'll just have to learn the material the old fashioned way.
